I have chevy bolt 2018 premiere. I noticed air pressure in the evening to be at 15psi. I called AAA and they found a nail and did the patch and put the air. Now for the last 3 days, air pressure shows at 42psi. So there is no leak.

When I asked at Samsclub, they recommend replacing the tire as it is run flat tire. Appreciate your opinion to use it or replace it.

My car has 10k miles. How many miles are these tires expected to be last far?

If the tire is holding air, why would you replace it?

Of course the tire shop is going to suggest you replace the tire.

Nail punctures are about the most common type of tire hazard. Patching or plugging is fine.

The Bolt's tires are not run flat tires. They're self sealing.

oh ok. good to know

The donut shop is going to recommend you get coffee with your donut too.

Thanks. I will use them without replacing but watch an eye on air pressure. I am assuming what it shows on the dashboard is reliable.

Keep us posted. I've been wondering how well the self sealing tires work.

 

[Nook]

I would be apprehensive, but carry a pump to help yourself or perhaps a book while you wait for a tow truck.

It's rare for a tire to fail catastrophically. You're much more likely to get a slowish leak that gives you time to respond. Tires can be driven on at surprising low pressure (at lower speed). I'd carry a pump just because they are super cheap, and the preferred way to recover from a puncture is to plug it and get going in 10min.

This topic has been discussed ad nauseum. People have varying levels of comfort. As someone that has had at least a dozen tire punctures in 20 years of driving, I'm comfortable without a spare tire. I have a cell phone and rarely am out of cell range. I've got friends/family that tend to be nearby the places I'm traveling. I carry a $20 tire inflator, plug kit, and pliers, so I can repair 95% of leaks within 10 minutes or less.

If I'm in the Montana backwoods in winter with no cell service, I'll want a spare tire or 2... and winter cloths, extra food and water, and a means of starting a fire.

They're not "run-flats". Run-flats allow one to drive on the tire with zero air pressure. The Bolt comes equipped with "self-sealing" tires, able to seal smallish leaks in the tread area, with goo applied to the inside surface.

Oops. That will teach me to not read *all* of the posts before adding my two cents...

 

[redpoint5]

I just assumed the OP had purchased aftermarket run-flats; either because they are a high value target at risk of assasination, a bank robber, or otherwise extremely paranoid about safety (prepper type).

That said, if the tires are in fact the "goop" ones, it was my understanding that tire shops remove the goop when they do a patch. Is it reasonable to believe the goop is either no longer in the tire, or otherwise compromised in the ability to self seal a puncture?

It appears from the Michelin instruction PDF that the goop is not removed, even at the puncture site. I'd just use a plug kit, rather than going to the tire repair shop. The result is very similar.

A couple of months ago I ran over a large and thick pencil sized "bolt" with my Bolt...and it punctured the tire which then went completely flat. It was repaired by the dealer with no problems since.

 

[Usain]

The same thing happened to me with about 40K miles on the tires. The dealership patched the tire and I've been good to go ever since.

I now have 50K on the tires and expect to get at least 60K. The tread is holding up very well.

Exactly. Here's the thread in which "tirenerd" posted the repair procedure. There's a lot of misinformation among even tire shop pros about how to deal with these tires, so IMHO it's worth printing a copy and keeping it in the car in case you get someone who claims the tires can't be patched.

 

[redpoint5]

Ah, I didn't know it was a smooth coating in the tire. I just imagined green goop sloshing around. That explains how these self-sealing tires don't muck up the TPMS.

The OEM tires are garbage. I don't know who approved them but I hated them from day one.


Last week I went over a pothole in a parking lot going 3 mph and my sidewall was punctured. This was the second time I lost a tire due to a sidewall failure. That was the last straw.

Yesterday my new Riken Raptor's came in and after 100 miles so far, they're amazing. To me, ride quality has improved as well as performance.

 

[sukumark]

sorry for the confusion. I really don't know what type of tires I had. I took service from AAA two times. First AAA guy told those are run-flat tires. When I called a second time to fill the air, he said he can patch for $20 and he does all the time and it fixes.
I really never saw what patch means. He took off the nail and made a bigger hole and filled it with some rubber. So far from 3 days, it maintained 42PSI. I see in another thread to put something from the tube. He did not use anything like that. He initially put more than 60psi. I told him to take off and make it to 42.

Two times when puncture happened for other cars, Costco recommended replacing both times. Typically, they don't recommend the patch.

How many miles are they rated to last far?

Over the weekend my wife drove our Bolt on Friday from North of Sacramento down to Scotts Valley to visit some friends. Ok all was well she arrives on Friday; then I get an alert from Onstar on Saturday afternoon telling me that the passenger side front tire was down to 26 lbs. I'm like ok that's weird. Called her and she took the Bolt over to a tire shop and had them check it out ... they pulled a screw out of the tire and patched it. Now what would have happened without Onstar? She would have had a flat tire on Sunday when she was about to leave ... would have had to call AAA ... would have had to find a tire shop that was open on Sunday. Super glad that BoltEV has the extended 5 year Onstar ... even if it's just the basic Onstar; it's still worth it. So first flat ... great notification from Onstar ... fixed! Onstar basic is free for the BoltEV for this 5 year period of time. Still had fix a flat in the back of the car but it's much better to get it patched.

Just got this the other day.
I had less than a mile to pull off the freeway before I was about to run on the rim.
As you can see, there was no "goop" oozing out attempting to seal the leak.

It took me over four hours to get back on the road after getting towed to a tire place to get it replaced.
Just kidding.
I had a spare and was back on the road in 20 mins.

My wife would notice a severely low tire and call me. Then I'd tell her where the tire plug kit and inflator were and walk her through the steps to repair and inflate the tire. 10 minutes later she'd have a permanent fix and be back on the road...

That gives me the idea that next time there is a puncture, I'll have her do the repair so later on she'll be able to do it without calling me in 5 minutes instead.
